LM’s comparison list between different

norms from Copper alloys

Please read below on the wished for trade-name in the left hand column, and get it translated into LM-language on the right-hand

column. The right hand column with our name is either identical in composition or a fully replaceable alloy with only minor

differences. The column in the middle states the norm and its country of origin.

With no marks in front of LM’s alloy = alloy is identical, with this sign “~” = alloy is very similar, fully replaceable.

純銅是玫瑰紅色金屬，表面形成氧化銅膜後呈紫色，故工業純銅常稱紫銅或電解銅。密度為8-9g/cm2，熔點1083°C。純銅導電性很好，大量用于制造電線、電纜、電刷等；導熱性好，常用來制造須防磁性干擾的磁學儀器、儀表，如羅盤、航空儀表等；塑性很好，易于熱壓和冷壓力加工，可制成管、棒、線、條、帶、板、箔等銅材。純銅產品有冶煉品及加工品兩種。 

概述

含鋁量一般不超過11.5%，有時還加入適量的鐵、鎳、錳等元素，以進一步改善性能。鋁青銅可熱處理強化，其強度比錫青銅高，抗高溫氧化性也較好。
